without taking from the efficiency of the gun,

and yet prevent the usual discomfort at the shoulder or other part of the body against which the butt of the gun is supported by the user; to provide for simplicity of structure and to facilitate its application to the gun;

and to attain certain advantagesas will more fully appear in the following description.

1The invention consists in the novel construction of the device, its parts and combinations and arrangements of parts, and in the peculiar application thereof to the gun, all as hereinafter described and pointed out with particularity in the appended claims.

In the accompanying drawings illustrating a practical adaptation of the invention,-

absorber Fig. 1 is a fragmentary view, in side elevation, of the breech and stock portion of -an ordinary gun with the shock absorber applied thereto;

Fig. 2 is a. fragmentary view, on an enlarged scale, the shock absorber being shown in longitudinal section and applied to the gun stock;

Fig. 3 is an outer end elevation of the shock Fig. l is a sect-ion taken on or about the line 4 4 of Fig. 2;

Fig. 5 is a section on the line 5-5 of Fig. 3; and

Fig. 6 is a View, in side elevation, illustrating a modification of the device.

Referring now to the drawings, the numeral 10` designates the breech portion of an ordinary firearm, such as a shot gun or a rifle, having the usual stock 11hand grip 12, and a hammer and trigger mechanism, which latter is shown only conventionally and designated generally by the reference numeral 13.

The device of the present invention is applied to the butt end of the stock 11 of the gun, this being done either at the factory where the gun is manufactured, or atl a time later, as a special attachment. In the former case the butt end of the stool: may be obviously prepared for the attachment of the device substantially as shown in the drawings, while in the latter case, the regular finishing plate or ferrule as usually pro-vided on a gun may be removed and the stock readily prepared for the reception of the shock absorber. V

As shown in the drawings,`the device coinprises, preferably, an inner plate 14 and an outer plate 15 which are normally spaced apart and'have springs 16 interposed between them, said springs being respectively secured,

Vas by soldering, welding, or other approved means or method of attachment, to the adjacent inner faces of said plates. l

In order that the plates 14, 15, may be of light weight, yet suiiciently' rigid to withstand the' usage thereof, they are preferably provided with inwardly extending, continuous, marginal flanges 17 and 18, respectively. Preferably, the marginal flange 18 of the outer plate 15 is somewhat deeper than the flange 17 of the inner plate 14, this being because the plate 14 is firmly supported on the end portion of the gun stock 11 in the manner to be presently described, whereas, the outer plate 15 having no such solid support, requires a deeper iiange to give it the necessary rigidity. In practice, the depth of the flanges 17 and 18 may be varied according to structural conditions and depending somewhat upon the normal distance between the meeting faces of the two plates 111 and 15 and the required clearance between the meeting edges of the marginal flanges 17 and 18 to permit the due compression of the springs 16 when functioning to absorb the recoil of the gun.

The inner plate 14 is preferably provided near its opposite ends with apertures 19 for the reception of screws Q0 by which it is attached to the end of the gun stock 11, the surface of which latter, of course, is planed or otherwise prepared so that said plate 14 rests in supporting contact therewith throughout. Preferably, the respective apertures 19 are arranged in triangular relation at each end of the plate 111, one of the apertures nearest the end of the plate being centrally disposed and the two other apertures being disposed transversely of the plate and located respectively near the Ymargins thereof. In order t0 facilitate the application and removal of the screws 20, in applying and detaching the device, the outer plate l5 is provided With apertures 2l somewhat larger in diameter than said apertures 2O in the plate le, this enlargement of the apertures 2l being to permit the passage of the screws freely therethrough andalso. to permit the insertion ot a screvv driver in applying and As shown in the drawings, the plates 14A` and lare provided. with prot-ubcrances.22`

on Vtheir inner taires, which are'located and',y

correlated so as to aiiord means' for rei 'lily positioning the respectivo springs 16 and serving to support said springs laterally to Va considerable advantage, said springs being preferably soldered or spot-Welded Vto the plates in th region ot the respective proy 1 r1 i i Y tuoerances. lhese. protuberances 22 may be provided on the plates in any approved or.

desirable manner, but itis preerableto lprovide them as shown by embossing or punching the plates from the opposite faces thereof.l

` ln most cases, the platesli andl will be substantially liatthroughout the entire ei;- tent thereof, but, obviously, in vsome instance-sv the outer plate l5 may be ciirvilineail or given the special contour sometimes provided at the butt end ot the stock otl the lirearins.

A modication of this character is illustrated in lhg.Y 6 of the dr Wings, wherein 'the outer plate l5 of the shock absorber is provided on its outer tace With a supplemental conformed plate 23 Which may be of metal, conipressed libre, terial. y

From the foregoing .slaecication it is readily apparent that a simpleand effective device may be produced and readily applied to a gun for the purposes intended, and, obvi-V Wood yor any other suitable inaously, the structure admits of considerable' modication and alterations Without depart: ing from the spirit and scope of the invention Y as defined by the appended claims.
